After the transition from Mellel3 to Mellel4, I've noticed that the display of auto-titles in the Outline pane has changed. I'm not sure of exactly what has been changed, but the result is that when many sub-levels are in use, the incrementing tab quickly makes perusing through the outline uncomfortable. This happens because most of the titles are on sub-levels and are cramped on the right-side of the pane, breaking into multiple lines. I insert a link to an image of an example.
